Patented May 10, 1932 f WILLIAM E. wmnor TOLEDO, OHIO VENTILATOR FOR cans Application filed zrul o, 1929.1 Serial-no. swans.

Still another object of the invention is to My invention relates to new and useful irnprovide a form of ventilator 'of special type J provements in ventilators for cars, such as grain] cars, cars in wh1ch flour is to be shipped, and other types of cars thatshould it will absolutely prevent any sweating of the andt o so position the same in agrain carthat P be ventilated.

As is well known to those skilled in the'art,

a part of the grain or flour is often spoiled when shipped in cars, due to the fact that there is a certain amount of moisture in the grain or in the other products in the car and, when the hotsun beats upon the roof of the car, the moisture will condense on the inner surface of the roof or, in other words, the

roof will sweat and the water will drop down onto the flour or the containers holding the flour or onto the grain and thereby cause considerable loss or damage.

,One of the objectsof the present invention, therefore, is to provideventilators,each with but one shutter, which are located'near the opposite diagonal corners of the car and up as near the roof as possible, so that a draft of air may pass over the grain or flour and from one end of the car to the other to thus prevent any sweating of the roof and the spoiling. of

Most of the freight car ventilators which are used today are placed in cars'where fresh or perishable products are used and the car is to be ventilated throughout its length and breadth. In the present'instanc'e, however, the invention contemplates usin ventilators located just near the top of t e grain or freight cars, so that a draft may simplypass over the load within the car.

Still another object of the invention is to provide a ventilator with a special form of supporting means or a locking bar for the shutter; together with a special, form of frame whereby it will be impossible for the lower end of the supporting bar to slipjfrom without the frame, even though thelocking pin is not inserted. Y

to the grain within the car.

Still another object of the invention is to provide an exceedingly simple typeof .ven-

car andthus save considerable damageor loss tilator having but one shutter and' having a V special form of frame and locking bar, so that the shutter may be conveniently" locked in either the open .or closed position-byfthe use of a locking. pin, but should even the lockingpin fail to .be used, theshutter is so constructed 7 that it will be securely held either in its open or closed position. i With these and other numerous objects in view, the inventionconsists in certainlnew and novel arrangements and .combination 'of parts, as will be hereinafter more fully 'described and pointed out in the claims.

Referring now to ,thedrawings showing.

an embodiment .of the invention,

g- 1 s? nature, of a car; i. 1 V

Fig. 2 is a.horizonta'l section, of a schematic nature,showing the car;

side'elevation, of aschernatic a Fig, 3 is an enlarged s1d elevation of one 7 corner of the car;

Fig. 4 is asectional view taken substantially through the line 44' on Fig. -7 with the shutter removed for the sake o'fl-cleare ness; ter in place;flf

Fig. 6 isan enlarged front view-of the Fig. 5 is a similar view but with the shutj ventilator showing the shutter in its closed with the usual grain doors 2, the roof 3, the I ladder 4 on one sideof the car and the lad der '5 on the other side'qofthe car (see Fig.

x 2) The sides 6 and of the 'ca'rare unbroken with the exception of the doors 2, while like wise the ends 8 and 9 of the car are unbroken.

However, as may be seen in Fig. l, I position a small ventilator 10 near the ladder 4 directly beneath the roof, and in a like man ner, position a further ventilator 11 on the opposite side 7 of the car and in the relative same position as the ventilator 10.

It will be understood that grain cars are packed nearly to their capacity, but not up to the plane in which these ventilators are located, and by so positioning these ventilators about to be described, it will permit a circulation of air over the top of the grain and thus prevent any sweating or dropping.

of moisture from theroof ofthe car when the moisture condenses. .I thus prevent the damage to the grain or .flour that would otherwise occur .in a nonventilated car.

In the same manner, if flour is shipped in the car and the barrels are piled one upon the other, they will not reach up to the plane of these ventilators and the air may circulate through these ventilators and thus prevent any sweating and resultant damage to the flour.

Having thus described the desired location of the ventilators and the purpose for which they were invented, more specific reference will be made to their structure and the manner .in which they operate.

It might be mentioned here, however, that the location of theventilators and the manner of ventilating the car form the subject matter of a divisional application filed by me on February 26, 1930 and bearing Serial Number 431,500.

Referring now more specifically to Figs. 3 to 9 inclusive and for the moment to Fig. 6., there will be seen one of these ventilators 10 and it will be noticed that it comprises a rectangular frame 12, while on the respective side piecesv13 of the frame, there may beseen the two wings or extension plates14, which may be scalloped, as at 1-5, and are provided with the opening'16 to receive the bolts that hold the ventilator to the sides of the car.

Referring now to Figs. 7 and .8, :it will be seen that the frame is provided with a top bar 17, which is also provided withthe opening 18 for the bolts, while a bottom rail 19 is also formed integral with the frame and with the wings 14, this rail being also provided with openings 20, so that the frame may be bolted on all four sides to the car, as shown in Fig. 3. In Figs. 4 and 5, I have shown a horizontal sectional View of the ventilator and the manner .in which the side 6 of the car may be out out as well as the inner sheathing 21, the frame being then fitted within the opening and securely bolted into place.

Referring again to figs. 7 and 8, the back wall 22 of the frame may be seen to extend from a plane even with the top rail 17 down to the point 23 where it slopes downwardly, as at 24, to the point where is merges, as at 25, with the lower rail 19.

As is also shown in Fig. 8, a water-proof paper 26 may be placed in front of this lower rail and likewise a filler 27 is shown between thesiding and the ventilator.

Still glancing at Figs. 7 and 8, there will be seen directly beneath the top rail 17 a projection 28 with the downwardly projecting rim 29, this small roof-like projection fitting under the siding of the car and projecting over the shutter of the ventilator, which shutter will beshortly mentioned. In a like manner,'resting upon the lower wall of the cut-out portion-of theside of the car may be seen a'bottom or floor of the ventilator which likewise has its extreme edge .31 projecting downwardly and over the siding.

As far as the invention has been disclosed, it will be seen that the front or top rail 17 and the bottom rail 19 as well as the two side wings 14 are all in the same plane, a portion of the frame extending in front of this plane to be enclosed within the siding of the car, while the remainder of the frame is'behind this plane and is enclosed within the car. Thus, the frame may be bodily placed within the opening in the siding from the inside of the car and then tightly bolted in place by the series of bolts 32, as may be clearly seen in Fig. 3. It willalso be seen that when the ventilator frame is once in place, it will be rigidly held and, .at the same time, the walls about the opening will be well protected from any rain and thus will not tend to rot.

It will. still further be seen that the major part of the frame is within the car and when the shutter about to be described is in its closed position, there is but a slight projection beyond the outer surface of the car, this projection simply being the end of the lockii lg bar and the lower edge of the shutter.

The upper portion of the frame is in the form of a longitudinal chamberwhich extends from one side of the ventilator to the other but, as may be seen in Figs. 7 and 8, there is no bottom for the chamber. On the other hand, small supporting lugs 33 are provided, so that a metal screen 34 may be within 3 grain or the flour will be caught in the screen and likewise any material from the car will not fall down into the ventilator frame and thus jam or prevent the shutter from operat- On the side walls of the frame 13, there may also be seen the small arcuate tracks or lugs 36, which act as a guideway for the louver or shutter 37, shortly to be described 1' in detail.

On the inner surface of each of these side or end pieces, there are formed the two small pivot bearings 37 which are the center points from which the arcuate tracks 36 are struck. Also extending across the ventilator from one side to the other is the small downwardly extending ledge 38, while rearwardly of the same and also extending entirely across the rear wall of the frame is the small ledge 39 and, as may be seen, the larger of the tracks 36 extends from the one wall 38 to the ledge 39 to thus brace the same.

Referring now for the moment to Fig. 6, there will be seen formed centrally of the frame the two guideways or tracks 40, which have the inwardly extending lips or lugs 41 at their outer ends, these guideways running from a point just beyond the inner edge of the frame upwardly and rearwardly to the small wall. 39, just heretofore mentioned.

Now having described the frame, the shut ter and the locking bar will next be described.

It might be mentioned here that the shutter and frame in their broadest aspect are of the well known Wine type, as shown in Patents, Nos. 1,298,136, granted to meMarch 25, 1919, 1,359,556, granted to me November 23, 1920, and 1,040,083, granted to me October 1, 1912.

It will be seen that the shutter comprises the two side pieces 42 which are formed integrally with the arcuate face or closure 43. The side pieces are reduced at their lower extremities. and are provided with the trunnions 44, which rest in the previously mentioned bearings 37. 7

As may be also seen in Fig. 6, there may be provided ribs 45 on the under surface of the shutter wall to brace the same, while add-itional'metal is allowed to flow, as at 46, to

provide strength where the side pieces merge wall 39, as shown in Fig.8. The pin'58 may with the shutter or closure wall 43.

The closure wall 43 also extends slightly outwardly beyond the side pieces 42, as ati47,

and these projections, it will be understood, come within the tracks formed by the arouate ribs 36 formed on the inner portion of the side pieces of the frame to thus prevent the same from arring out of position. The shutter is also provided in its central portion and on its outer edge with thetwo lugs 48, as also shown in'my previous patents, and between these lugs is fastened one end of a. locking bar 49.- The shutter per se is identical with the shutter shown in my previous patents mentioned.

Before describing this locking bar, it will.

in Fig. 8 to thus open the-ventilator and snow the 'air to" pass beneath this shutter, up

noticed that this bar 49' comprises the body portion 50 with the downwardly extending arm 51 (see Fig. 9), while at its rear end,

there is provided the enlarged elongated cylindrical portion or trunnion 52; It will also be noticed that this trunnion 52 is provided with the opening 53 therethrouglr Likewise, the forward end of the body portion is provided with anopening 54 as well as the arm 51 with the opening 55.

This locking bar may be ribbed, as at 56 and 57, to thus strong bar. l I

It might be herementioned that the frame, the shutter and likewise this'lo cking bar. are all castings, therefore, necessitating butlittle machining or skilled labor thereon,

Now looking at Figs. 6 to 9 inclusive, it will be seen that the forward end of the bar 1s permanently pivoted through the opening 54 to the lugs 48 of the shutter. The rear end of the bar with. the trunnion'52 fits within the guideways 40 and, when the shutter is in its closed position, a pin 58'is' passed through openings 59 in the ends of the guideways 40, through the opening 53 in the trunnion 52, and thus locking the shutter in its closed position. It will also be seen that even should this pin be not inserted, after thelocking bar is once'in position it cannot swing out of the frame, because the trunnion 52.will be held by the lips 41 at the ends of the guideways'40. When the shutter is in its open position, the same will be swung to the position shown provide a relativelylight but in'Fig. 8, the pin 58 having, of course, been removed and the rear end of the lockingbar will travel upwardly and impinge against the now be passed through the opening 55 in the arm 51 of the. locking bar, thus tightly locking the shutter in its open position.

' In this case also, should the pin not be inserted', the weight of the shutter and the way it is mounted will keep the same open and the V the wall 39 and with thelips. 41, and even though the pin be not inserted in either instance, the. shutter will remain where placed until again changed; V V From the' foregoing, it will be seen that I have provided a ventilator compri i g 3/ novelframe together with one of my old types of shutters'and with a new formiofj locking bar, thusproviding a ventilator of extremely simple construction. Also, I have provided a ventilator that is quickly and easily assembled easily installed, and may be quickly and easily operated to either one of its positions. i

It will be understood that although this ventilator is especially adapted for grain cars or for cars carrying flour or even for cars carrying perishable products, it may also be used with other structures where a simple, small and efficient ventilator is desired and wherein it will be impossible for anyone of evil bent to enter the same. 7

- Lastly, it will be seen that after the patterns have once been made, the castings may be made at a relatively low cost and the entire ventilator assembled on a cheap, commercial scale.
